Specification of Letters Patent.

Patented Sept. 9, 1919.

Application filed November 1, 1917. Serial No. 199,691.

1' b all whom it may concern:

Be it known that I, ELMnR II. Trronrrson, a citizen of the United States, residing at lVlIanitowoc, in the county of Manitowoc and State of lVisconsin, have invented certain new and useful Improvements in Keel- Blocks, of which the following is a spec1- fication.

This invention relates to ships and it 1s the dominant object of the invention to provide an improved keel block for use in supporting ships during the construction oi the same on ways, which can be readily assembled for arrangement beneath a shlp and when desired, can be equally and readily disassembled. to cause disengagement thereof from the ship, thus, facilitating launching of the same. i

The improvements in the details and ar rangeinent of parts will be apparent from an inspection of the accompanying drawings, in connection with the specific description hereinafter contained, and wherein the preferred embodiment of the invention is disclosed for the purpose of imparting a full understanding of the same.

In the drawings Figure 1 is a side elevation of the improved keel block,

Fig. 2 is a vertical longitudinal section therethrough, and

Fig. 3 is a vertical transverse section through the same.

l l'aving more particular reference to the drawings, the improved keel block includes a lower body portion indicated in its entirety by the numeral 1, which portion is formed from side sections 2 having transversely disposed openings and slots arranged therein and adapted to be alined in order that bolts 3 may be passed therethrough and the sections of the lower portions thus connected. Washers or like bearing elements are arranged upon the outer sides of the sections 2 and engaged by the bolts 3 and their nuts.

As will be noted, the upper surfaces ofthe' sections 2 are inclined and beveled in opposite directions as indicatedby the numeral l, thus forming a substantial V-shaped inclined way, the purpose of which will be presently apparent.

Copies 01 this patent may be obtained for A rider section 5 is provided and includes a block having the lower portion thereof inclined and V-shaped as indicated by the numeral 6, whereby the same Will be received in the V-shaped way formed in the upper surface of the lower portion 1.

Due to the arrangement of the rider section 5 upon the lower portion it will be readily understood that by sliding the same thereover the height of the keel block in its entirety will be increased and as a consequence, the same will serve to engage and maintain a ship in proper position during construction of the same on ways or like supports. /Vhen desiring to disengage the improved keel block from the bottom of the ship it is only necessary to disassemble the lower portion by removing the bolts 3 from the transverse openings and slots formed therein. In this way, the block is positively disengaged from the bottom of the ship in a quick and effective manner.

Arranged between the sections 2 is a metal wear plate.

lvlanifestly, the construction shown is ca pable of considerable modification and such modification as is within the scope of my claim, I consider within the spirit of my invention.

A keel block comprising a side section having their upper faces inclined toward each other and longitudinally to form a sloping substantially V-shaped pocket therein and having alined transverse openings in their intermediate portions and alined slots 1n and opening through their end portions, bolts passing through said openings and end slots to detachably connect the side sections, and a rider section having a substantially V-shaped lower portion slidable in the V- shaped pocket formed in the upper faces of said side sections, said side sections being of lengths greater than the rider section to allow sliding of the same longitudinally of said sections.

In testimony whereof, I affix my slgnature hereto;

ELMER H. THOMPSON.
